the Stock Option Agreements, the Stockholders are willing to agree, severally 
but not jointly, to vote in favor of adopting the Merger Agreement and 
approving the Doubletree Merger, upon the terms and subject to the conditions 
set forth herein.

          NOW, THEREFORE, in consideration of the foregoing and the mutual 
covenants and agreements contained herein, and intending to be legally bound 
hereby, the parties hereby agree, severally and not jointly, as follows:

          Section 1.  VOTING OF SHARES.  Until the termination of this 
Agreement in accordance with the terms hereof, each Stockholder hereby agrees 
that, at the Doubletree Stockholders' Meeting or any other meeting of the 
stockholders of Doubletree, however called, and in any action by written 
consent of the stockholders of Doubletree, such Stockholder will vote all of 
its respective Shares (a) in favor of adoption of the Merger Agreement and 
approval of the Doubletree Merger and the other transactions contemplated by 
the Merger Agreement, and (b) in favor of any other matter necessary to the 
consummation of the transactions contemplated by the Merger Agreement and 
considered and voted upon by the stockholders of Doubletree (or any class 
thereof).  In addition, each Stockholder agrees that it will, upon request by 
Promus, furnish written confirmation, in form and substance reasonably 
satisfactory to Promus, of such Stockholder's support for the Merger 
Agreement and the Doubletree Merger.  Each Stockholder acknowledges receipt 
and review of a copy of the Merger Agreement.

          Section 2.  TRANSFER OF SHARES.  Each Stockholder represents and 
warrants that it has no present intention of taking any action, prior to the 
termination of this Agreement in accordance with the terms hereof, to, 
directly or indirectly, (a) sell, assign, transfer (including by merger, 
testamentary disposition, interspousal disposition pursuant to a domestic 
relations proceeding or otherwise by operation of law), pledge, encumber or 
otherwise dispose of any of its respective Shares, (b) deposit any of its 
respective Shares into a voting trust or enter into a voting agreement or 
arrangement with respect to any such Shares or grant any proxy or power of 
attorney with respect thereto which is inconsistent with this Agreement or 
(c) enter into any contract, option or other arrangement or undertaking with 
respect to the direct or indirect sale, assignment, transfer (including by 
merger, testamentary disposition, interspousal disposition pursuant to a 
domestic relations proceeding or otherwise by operation of law) or other 
disposition of any Shares.

                                       2



          Section 3.  NO SOLICITATION.  Prior to the termination of this 
Agreement in accordance with its terms, each Stockholder agrees (a) that it 
will not, nor will it authorize or permit any of its officers, directors, 
employees, agents and representatives to, directly or indirectly, initiate or 
solicit any inquiries or the making of any Acquisition Proposal and (b) that 
it will notify Promus as soon as possible (and in any event within 48 hours) 
if any such inquiries or proposals are received by, any information or 
documents is requested from, or any negotiations or discussions are sought to 
be initiated or continued with, it or any of its affiliates. 

          Section 4.  TERMINATION.  This Agreement shall terminate upon the 
earliest to occur of (i) the Effective Time or (ii) any termination of the 
Merger Agreement in accordance with the terms thereof; provided that the 
provisions of Section 7 shall survive any termination of this Agreement, and 
provided further that no such termination shall relieve any party of 
liability for a breach hereof prior to termination.

          Section 5.  REGISTRATION RIGHTS.  Until the termination of this 
Agreement in accordance with the terms hereof, no Stockholder will exercise 
any of its rights to request or require registration of any securities under 
the Incorporation and Registration Rights Agreement dated as of December 16, 
1993, as amended on June 30, 1994, February 27, 1996 and November 8, 1996, by 
and among Doubletree and certain stockholders of Doubletree (the 
"Registration Rights Agreement).

          Section 6.  SPECIFIC PERFORMANCE.  The parties hereto agree that 
irreparable damage would occur in the event any provision of this Agreement 
was not performed in accordance with the terms hereof and that the parties 
shall be entitled to specific performance of the terms hereof, in addition to 
any other remedy at law or in equity.

          Section 7.  MISCELLANEOUS.  

          (a)  This Agreement constitutes the entire agreement between the 
parties hereto with respect to the subject matter hereof and supersedes all 
prior agreements and understandings, both written and oral, between the 
parties with respect thereto.  This Agreement may not be amended, modified or 
rescinded except by an instrument in writing signed by each of the parties 
hereto.

          (b)  If any term or other provision of this Agreement is invalid, 
illegal or incapable of being enforced by any rule of law, or public policy, 
all other conditions and provisions of this Agreement shall nevertheless 
remain in full force and effect.  Upon such determination that any term or 
other provision is invalid, illegal or incapable of being enforced, the 
parties hereto shall negotiate in good faith to modify this Agreement so as 
to effect the original intent of the parties as closely as possible to the 
fullest extent permitted by applicable law in a mutually acceptable manner in 
order that the terms of this Agreement remain as originally contemplated to 
the fullest extent possible.

          (c)  This Agreement shall be governed by and construed in 
accordance with the laws of the State of Delaware without regard to the 
principles of conflicts of law thereof.

                                       3



          (d)  Notwithstanding anything herein to the contrary, the covenants 
and agreements set forth herein shall not prevent any of the Stockholders' 
designees, partners or affiliates serving on the Board of Directors of 
Doubletree from taking any action, subject to the applicable provisions of 
the Merger Agreement, while acting in such capacity as a director of 
Doubletree.

          (e)  Notwithstanding any provisions hereof, none of the obligations 
of any Stockholder under or contemplated by this Agreement shall be an 
obligation of (i) any officer, director, stockholder, limited partner, 
general partner or owner of such Stockholder, or any of their respective 
officers, directors, stockholders, limited partners, general partners or 
owners, or successors or assigns or (ii) any other Stockholder.  Each 
Stockholder shall be the only person or entity liable with respect to its 
obligations.  Any monetary liability of a Stockholder under this Agreement 
shall be satisfied solely out of the assets of such Stockholder.  Each 
Stockholder hereby irrevocably waives any right it may have against any such 
officer, director, stockholder, limited partner, general partner, owner, 
successor or assign identified above as a result of the performance of the 
provisions under or contemplated by this Agreement.  Nothing in this Section 
7(e) shall prevent Promus from obtaining specific enforcement of the 
obligations of any Stockholder under this Agreement.

          (f)  This Agreement may be executed in counterparts, each of which 
shall be deemed an original and all of which together shall constitute one 
and the same instrument.          

                                       4
